Let A(1,1), B(5,2) , D(3,5), ...................X(2,8)

how can find the furthest point from the two point A and B in this plane

[darova]

The question is unclear. Can you make a simple drawing or something?

[Hassan]

if A and B are two points in this plane

how can find the furthest point ( ecludiance distance) from A & B

or

which point is the furthest from them A & B "Which point is the farthest? "

[darova]

You want to find F point. Is it correct?

[Hassan]
